The episode as NWS BRO wrote it up.
The coastal counties and Zapata County saw a brief respite and temporary improvement in drought conditions, as the effects from rains during the middle the month, courtesy of a southwest moving upper level disturbance that originated in the Ohio Valley and ended up in northwest Mexico. The disturbance ultimately brought a several day period of locally unsettled weather mainly between the 16th and 20th, began to be felt. Where rainfall was much more sparse, drought conditions continued to hold steady or worsen. The high pressure ridge aloft quickly returned and brought back summer time heat and dry conditions across the area the last week of the month.
